Block

How it is used

Blocks are produced, mined, validated and added to the chain. Engineers talk about block time (how often a new block appears), block height (its position in the chain) and block size. A transaction is said to be included in a block.

Example sentences

1. Your transaction was included in the next block, so it should appear in your wallet now.

2. Block time on this network is about two seconds.

Related terms

• blockchainA shared digital record of transactions that is copied across many computers. New data is added in blocks, and each block is linked to the one before it, so past records are very hard to change.
• hashA short, fixed-length code produced from any piece of data by a mathematical function. Even a tiny change to the data produces a completely different hash, which makes tampering easy to detect.
• block rewardThe new coins a miner or validator receives for adding a block to the chain. On many networks, the transaction fees in that block are paid on top of the reward.
• confirmationProof that a transaction has been included in a block. Each new block added after it counts as one more confirmation, and more confirmations make the transaction harder to reverse.
• block explorerA website that lets anyone search a blockchain and see blocks, transactions, addresses and smart contracts in readable form.
